As might be anticipated, Amen is not a stranger to controversy. In 2005, on Quackwatch.org, a nonprofit that investigates health-related frauds, myths, fads and fallacies, Dr. Harriet Hall, a retired family physician, outlined concerns regarding Amen’s practices. In addition to those I’ve mentioned, Hall was critical of Amen’s unsupported claims that SPECT scanning provides “guidance in the application of specific medications or other treatments such as supplements, neurofeedback, transcranial magnetic stimulation, and hyperbaric oxygen therapy.”
